You need a Workbook_Change event macro for that. The code you would write
in that macro should first check that the change occurred in a cell within
the range you want. Then the code would check the value of what you
entered, and if it exceeds some value the code would reduce the value to
what you want and insert the difference, or whatever you want, into some
other column. Writing the code is left to the student. HTH Otto

I am doing a fairly easy programme on excel. It is a catchment runoff, and
evaporation calculator. But i would like to place a limit on a cell, and
have
that exess go into another column, is this possible? EG 75 rainfall, soil
can
hold only 10mm more. SO 10mm INFILTRATES, ie that cell should have a limit
of
the max soil moisutre, the other 65mm RUNOFF's and thats a different
column.
ANYBODY PLEASEEEEEEEEEE!!!! lol
